SELF-CLOSING TOP IEO'R CONTAINERS.

Application filed January 26, 1925., Serial No. 4,785.

To all whom it may concern:

Be it known that I, \VILIJAM C. NEN- STIEHL, a citizen of the United States,'a'nd a resident of Wilmington', county of New Castle, State of Delaware, have invented certain Improvements in Self-Closing Tops for Containers, of whichthe following is a specification. v

My-invention relates to certain improvements in self-closing tops .for containers used for materials such as tooth pastes, shaving creams, tooth powders, perfumed liquids and other substances.

One Object of my invention is to provide closed, yet allowing for the manipulationof the lever while the container is held in the hand. The moment the lever is released the valve moves back to the closed position. i

A further object of my invention is to make the valve, the spring and the lever in one piece of sheet metal. These objects I attain in the following manner, reference being had to the a'ccompanying drawing, in which Figure 1 is a perspective view of the upper portion of the container, illustrating my invention; Fig. 2a a transverse sectional view; Fig. 3 is another transverse sectional view; Fig. 4 is a plan view with the valve removed; Fig. 5 is a side view of the valve detached; Fig. 6 is a perspective end View of the valve detached; Fig. 7 is a side view of the cork packing; Fig. 8 is a View of the edge of the cork packing.

Referring to the drawings, 1 is the container having on top a valve seat 2. In the top of the container is a hole 3 and on one side of the top is a slot 4, in which the but it will be understood that the spring may be secured to the container in any suitable manner. 5 is a projection from the means for keeping the'container normally" spring member of the valve is clinched fast,

tion. 8 is the lever member of the valve '6 and the spring 7, which when pressed down on the container moves the valve upward to an open position. 9 is the cork packing used between the valve seat 2'and the valve 6 to give the valve a perfect seat. point at which the material escapes.

The operation is as follows :-W'hen used with a collapsible tube the container is grasped by the hand with the forefinger in contact with the lever and, by pressing down on the lever with the forefinger, the valve 1Ov is the,

is moved upward to the open position, when I the material can be squeezed through the opening, but as \soon as the forefinger is.

released the spring tongue will return the valve to the normal pos1t1on,-as in Fig. 2,

cutting oil the flow of material and closing the receptacle. j When used with non-collapsible containers, the container is grasped by the hand with a the forefinger in contact with the lever and by pressing down on the lever with the forefinger, the valve is moved upward tothe open position, when the material can be shaken from the container, but as soon as the "forefinger is released the spring tongue will return the valve to the normal closed position, as in Fig. 2, cutting off the flow of material and closing the receptacle.

Having thus described my invention-, what I claim as new, and desire to secure by Letters Patent, is:

The combination with a container having an outlet hole in the top thereof and a slot inthe top adjacent said hole, of a valve.

having a depending spring with a projection on the end thereof and a lever all constructed in one piece of sheet metal, the Valve being mounted on the top of the container and adapted to move away from the outlet hole, said spring being bent downward between the valve and the lever, the projectionend of the spring extending downward into said slot, and the outside wall of the container top adjacent the slot being clinched over the projection on the end of the spring thereby holding the valve fast and normally in a closed position.

In testimony whereof, I have signed my name to this specification.
